Coursera is one of the largest companies offering “MOOCs” — that is, massive open online courses. Launched in 2012 by two Stanford professors, Coursera partnered with universities to offer college courses for free. In the years since, Coursera has grown to offer certificates and even full college degrees for a fraction of the cost of on-campus degrees offered by its partner universities. It has also expanded into offering employee training for businesses. Coursera CEO Jeff Maggioncalda says he thinks online learning could just be the future of higher education.
